So here we are back at the Donmar Warehouse, back in a Phyllidia Lloyd production, back in prison, back with an all-female cast and, sadly, back to howls of protest emanating from the comment boards. Despite the compelling evidence of last year’s Julius Caesar for the benefits of seeing women perform ‘male’ roles, including Harriet Walter putting in the performance of the year as Brutus, little seems to have changed and so the old arguments have been dusted off and trotted back out.

To incite further ire Phyllidia Lloyd has radically altered Shakespeare’s original text. This is not a snip here, a cut there. This is Henry IV Parts I and II, totalling almost six hours of performance, smashed together and pared down to 120 minutes. That really is an audacious move.

It is also a smart one. May directors have discovered how difficult it is to change Shakespeare by working around the fringes; if you are looking to show something new within something old then far better to prune the excess foliage until what is obscured below is revealed. Shakespeare’s talent did on occasion lead to an explosion of brilliance, his imagination working so fast that one play can contain more plot strands than most writers can work into several; this is his genius but the audience, unpicking the complexity of plot and language, can lose focus on anything that isn’t centre-stage.

In Henry IV productions almost all exclusively focus on the Hal/Falstaff dynamic; it is the interesting complexity of the prince we know will become the near-mythic Henry V, and his relationship with the greatest tragicomic creation of his age. However in Lloyd’s reduction we see this become a play that focuses on the dynamics of a father with two sons, and a son with two fathers.

With Harriet Walter as the dying king it makes sense to ensure that the most is made of an actor of her calibre. By barely cutting Henry IV’s lines, it makes the role far more central to the play. Much of Falstaff’s activities outside of Hal’s orbit are cut and this results in a balancing of Falstaff and Henry IV and creates two much clearer allegiances for Hal.

The resulting time is given over to the rebels, and in particular Jade Anouka’s sparky Hotspur – a brilliant performance that brings to vivid life Frank Kermode’s description of Hotspur’s lines being ‘anti-poetry, a contempt for poetry as flummery and affectation’. By stripping the text it aligns Hotspur and Hal as the son the king wished he had and the son that he wished he hadn’t. It also allows room for Hotspur’s wife, Lady Percy (Sharon Rooney), to shine. The scenes with her husband and mourning his death are often lost amid the action but here they are in focus and Rooney gives a heartbreakingly tender performance of someone who loses a husband and then desperately seeks to avoid losing a father.
